recently, offshore and ocean engineering have been dealing with novel materials that play a significant role in reducing the weight of structures used in the ship construction industry. 5xxx series of aluminum alloys are of the novel alloys are suitable for construction of ship hulls and the topside structures of offshore platforms. within different 5xxx aluminum alloys, aa5083 is of great impo...
complex culverts have a change of section (transition) at one or more positions along their lengths. the hydraulic performance cannot be estimated using simple culvert methods because the transition may change the control point. by modeling the flow through a transition as free flow, sluice flow, pipe flow and treating a complex culvert, as a series of simple culverts with the appropriate hydra...
We construct unramified central simple algebras representing 2-torsion classes in the Brauer group of a hyperelliptic curve, and show that every 2-torsion class can be constructed this way when the curve has a rational Weierstrass point or when the base field is C1. In general, we show that a large (but in general proper) subgroup of the 2torsion classes are given by the construction. Examples ...
In this brief note, we prove the following two Artin-Schreier curves are supersin-gular.
Abstract In this research, a radial basis function artificial neural network (RBF-ANN) model was developed to predict the hot deformation flow curves of API X65 pipeline steel. The results of the developed model was compared with the results of a new phenomenological model that has recently been developed based on a power function of Zener-Hollomon parameter and a third order polynomial functio...
The aim of the present study is the prediction of critical conditions (including critical strain and flow stress) for the initiation of dynamic recrystallization during thermo-mechanical processing of plain carbon steels. For this propose, torsion tests were conducted at different temperature (1050, 1100 and 1150˚C) and strain rates (0.002, 0.02 and 0.2/s). All flow curves showed a peak st...
